The single camera can acquire digital images of a retinal region of an eye, and digital images of a corneal region of the eye. The camera includes a first combination of optical elements for making said retinal digital images, and a second combination of optical elements for making said corneal digital images. In a preferred embodiment, a portion of these elements are shared elements including a first objective element of an objective lens combination, a digital image sensor and at least one eyepiece for viewing either the retina or the cornea. Also, preferably, the retinal combination also includes a first changeable element of said objective lens system for focusing, in combination with said first objective element, portions or all of said retinal region at or approximately at a common image plane.
